大师兄，买了你的书发现几个问题

终极YB易

一，没有讲解怎么视频合并
二，ffmpeg.exe -y -i 333333.mp4 -pix_fmt nv12 -vcodec h264_qsv -an new.mp4
      这条命令 出现错误提示  我用的是I7 CPU
Error initializing an internal MFX session: unsupp
orted (-3)
Error initializing output stream 0:0 -- Error while opening encoder for output s
tream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

三，ffmpeg.exe -y -hwaccel cuvid -vcodec h264_cuvid -i 222222.mp4  -filter_complex [0]scale=640:360 -vcodec h264_nvenc  new1.mp4
       这条命令 出现错误提示
Impossible to convert between the formats supported by the filter 'graph 0 input from stream 0:0' and the filter 'auto_scaler_0'
Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented
Error while processing the decoded data for stream #0:0
Qavg: 135.112
2 frames left in the queue on closing
Conversion failed!

不添加滤镜又正常
ffmpeg.exe -y -hwaccel cuvid -vcodec h264_cuvid -i 222222.mp4 -vcodec h264_nvenc  new1.mp4

目前发现这3个问题



求大师兄解答

硬件环境方便提供来不？
qsv是否正常安装了？
